Methods and Results— After AV nodal ablation, mongrel dogs were randomized to receive 16 weeks of VDD pacing at the RV apex, RV septum, LV apex, or LV septum (transventricular septal approach).

INTRODUCTION Surgical treatment of multiple ventricular septal defects (VSDs) is complex, particularly with anterior and apical locations. Normally, several interventions are required, increasing the ...

Methods: Patients receiving their first pacemaker for advanced atrioventricular block, with the atria in sinus rhythm, were randomized to receive apical (Group A) or septal (Group S) ventricular ...

Background: Right ventricular (RV) septal pacing has been advocated as an alternative to RV apical pacing to avoid long term detrimental effects. There is conflicting evidence on the benefits of RV ...

Figure 1. (Aa) Preoperative transthoracic echocardiography (TTE): left ventricular (LV) septal thickness of 20mm; (Ab) the extent of ventricular aneurysm; (Ac) left ventricular outflow tract (LVOT) ...

At six months follow-up there was a similar decrease in LVESV from baseline in both the septal and apical groups (-25 vs. -29 ml respectively; p=0.79).

Most reports on the differences between septal and apical pacing have not considered this facet, [1–3, 25–27] which remains important because the ideal pacing site has not been definitively ...
